Hey guy's I am new to the group but not ne to the gm 8 speed transmission, I know they shift better with the Mobil one transmission fluid, So my demand upon purchase the dealer is goin to flush my 2019 Colorado ZR2 transmission, Has anyone else here ever had their transmission flushed, I jus did not want to wait for the infamous 8 speed shutter, I know every 8 speed out there will do it it's just matter of time, So whats yur thoughts?
